In the early 1990s, Chen Jianjun, a young man from northern Jiangsu Province, went to the city to work with a few dozen yuan and worked exhaustingly on the assembly line of a garment factory. However, he relied on his natural market intuition to discover business opportunities in the price difference between urban and rural clothing. He raised money to resell low-end clothing, but he ran into trouble because he didn't understand the market. Fortunately, Zhao Hongmei, a self-employed businessman, gave him guidance. After that, he relied on his intuition to predict popular styles and started from a street stall to a small shop, but he encountered the monopoly and suppression of the veteran businessman Zhou Zhiqiang. Chen Jianjun relied on his accurate judgment to seize supply sources and expand channels, and worked in the clothing, small commodities and other industries. In the business trend of reform and opening up, he withstood the squeeze and gained a foothold step by step, writing a 90-year-old business legend that belongs to a small person.
